Referring to fig. 1, 2, 3, 4 and 7, an embodiment of the present invention provides a drill rod delivery device 1, including: a derrick 10; the hoisting assembly 20 comprises a winch unit 21 and a lifting rope 22 which are arranged on the derrick 10, one end of the lifting rope 22 is wound on the winch unit 21, and the other end of the lifting rope 22 is arranged in a falling mode from top to bottom; the lifting assembly 30 comprises a righting sleeve 31 arranged on the lifting rope 22 and a lifting hook 32 arranged at the dropping end of the lifting rope 22, and the righting sleeve 31 is provided with a first righting hole for the drill rod 2 to pass through; and a transfer assembly 40 rotatably disposed at the derrick 10 and having a first position at one side of the derrick 10 and a second position corresponding to a wellhead position for drilling, the transfer assembly 40 being configured to take the drill rod 2 at the first position and move the drill rod 2 to the second position.

The drill rod delivery device 1 provided by the embodiment of the invention is used for rapidly delivering the drill rod 2 in the horizontal attitude on the ground to the center of the wellhead of the derrick 10, enabling the drill rod 2 to be in the vertical attitude, and facilitating the subsequent joint operation of a top drive or a power water faucet installed on the derrick 10. The whole process of delivering the drill rod 2 does not need to manually carry the drill rod 2, so that the labor intensity of operators can be reduced, the drilling time is saved, and the operation is safer. The normal work of the drilling machine cannot be influenced by the delivery of the drill rod 2, the drilling process of the drilling machine and the delivery process of the drill rod 2 can be synchronously carried out, and the drilling time can be saved.

In the embodiment of the present invention, the hoisting assembly 20 includes a winch unit 21 and a lifting rope 22, the lifting rope 22 may be a steel wire rope, a nylon rope, an iron chain, or the like, and the winch unit 21 is used to wind and release the steel wire rope when the lifting rope 22 is the steel wire rope in the embodiment of the present invention. The lifting assembly 30 is arranged at the end of the wireline remote from the winch unit 21, and the distance between the righting sleeve 31 and the lifting hook 32 is less than the length of a single drill pipe 2. Lifting hook 32 can lift drilling rod 2 and spacing, and it can have single claw that colludes, also can have a plurality of claws that collude, and when lifting hook 32 had a plurality of claws that collude, a plurality of claws enclosed and close the bearing space who forms drilling rod 2. In the following embodiments, a case where the lifting hook 32 has a single hook is exemplified. When the drill rod 2 is hoisted (usually, a plurality of drill rods 2 are stacked on the rack in a 'flat' posture), an operator does not need to lift the drill rod 2, the operator firstly holds the centering sleeve 31 to enable one end of the drill rod 2 to penetrate through the first centering hole of the centering sleeve 31, then holds the lifting hook 32 to enable the lifting hook 32 to be hooked into the central hole at the other end of the drill rod 2, and the drill rod 2 is limited between the lifting hook 32 and the centering sleeve 31 and can move along with the steel wire rope.
